I have been watching this artist and their brush always fascinates me . So I ( least) tried replicating the brush . It didn’t work. So I was wondering can anyone replicate the brush since I don’t really understand how brush making works.
Here the artist (ref)
Did you try this brush already? It seems to be very close to the one you are searching for.

looks to be very similar to my brush! in this clip studio brush, the ink gets darker toward the outside edge of the line, whereas mine doesn’t (i’m not aware of any way to have it do that besides using a predefined brush tip), and it’s a little rougher. you can make it rougher by adjusting the ‘fuzzy dab’ curve in the brush editor under ‘size’ and ‘rotation’, there are also density and randomness options under the ‘brush tip’ category that might get it a little closer.
Ok one more question. Do you know any other brushes that resemblance this

I would check out these sets:
Mikhailasmo’s Inking Brush Set 
Expressive Inks bundle brushes for krita 5
A stroke of genius:
Brush set : Rusty Dip pens - traditional inking Simulation for manga and comic

Very interesting I find:
Cas van de pen demo brush recreation
Worth a look - or two …:
Sharpie Marker
This one may be worth a look too:
Awez Brush Bundle Bonanza
As well as this one:
“WhiteBear’s Brush Arsenal | The Secret Behind My 4-Year-Old Brushes Revealed!”
Brush set : Line Art without pressure sensitivity (mouse and touch)
By the way, if you want to pencil it beforehand, the best set I currently know (but it got close followers in between):
Sketch V2. (SK2) Pleasure to draw. Including colored pencils and blenders
There are even more, but maybe you learn one thing from this huge collection: “The most important thing with achieving a look or style, is the artist wielding the brush and setting it up correctly!”, this should mean, even if you had the exact brush preset artist XYZ uses, you need at least some experience to achieve the same results with that preset. And this is simply because everyone holds its stylus different, applies different pressure, etc., and this makes it so difficult.
It is much more important to find a brush which makes you feel “home”, this will allow you doing things you never thought beforehand. Sometimes a little adjustment here or there and you’ll be doing wonders.

to add again, there are also these gege akutami inspired brushes who was the illustrator of jjk previously
